WASTE-VALVE-CONTROLLING DEVICE.

Application fi1ec1 January 8, 1924. Serial No. 684,982.

To all whom it may concern:

Be it known that I, CARL E. DUREY, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in WVaste-Valve-Controlling Devices, of which the following is a specification.

This invention relates to wash-basins for running water, in which provision is made for an automatic overflow in case of a flow or leak through the bibb, with the wasteplug closed, and the object of the invention is to provide a simple and efficient device for opening and closing said waste-plug or valve.

The invention is fully disclosed in the description and claims following, reference being had to the accompanying drawings, in which:

Fig. 1 is a side elevation of a device embodying the invention, the parts contiguous thereto being shown mainly in section. Fig. 2 is a vertical section of the operating knob and its connections. Fig. 3 is a similar section, showing the waste-valve and the parts of the controlling device connecting therewith.

In the drawing, the numeral 5 denotes a wash-basin of a familiar type, provided with an overflow channel 6 in communication with the waste-pipe 7' and 7 through openings 8 in the valve-seat 8 attached to the lowest portion of the basin. This seat is provided with a plug valve 9, all of the foregoing being of familiar construction. This invention, as above indicated, has especial reference to means for opening and closing the waste-valve.

The valve 9 is provided with a depending stem 9 mounted slidably in a guide-bearing 7 a forming a part of the valve-seat assembly. This, with the lateral wings 9 serve to guide the valve in a true movement up and down. To the stem below the lower guide is at tached a slotted collar 10, clamping the stem by means of a screw 11. The screw also serves as a pivot for the eye 12 of a flex ible pushing and pulling member 12, which may be, as herein shown, a simple wire of spring brass, or other metal or material not subject to rust.

On the rear apron of the basin is mounted the device for operating this pull-and-thrust wall of the valve-seat 9, is a tube 17 serv ing as aguide for the operating flexiblemember. The upper end of said flexible member extends up through the tubular shank 18, of the operating knob 19, and is secured in proper position by a set-screw 20. In practice it is set to leave a little gap between [the base of the knob and the guide-flange,

so that a downward pressure on the knob will insure the closing of the waste-valve. Lifting the knob of course lifts the valve straight up, and this lift is limited by the guide-bearing 7 which serves as a stop for the clamp-collar, as will be apparent by reference to Fig. 3.

For convenience in assembling the device the waste-valve and its stem are preferably made separable, a simple and satisfactory connection of the parts being the stem with a groove at 9 and a set screw 21 in the hub of the valve.

In practice the guide-tube 17 is permanently attached to the valve-seat member, as by soldering at 22. The fixture as a whole is easily and quickly asembled and mounted by first attaching the valve-seat and knobguide to the basin then running the thrustwire through its guide from below, and finally connecting the wire and clamp-collar to the valve-stem, and the upper end of the wire to the knob.

The device is attachable to any lavatory having a waste and overflow of the type herein designated. Among its advantages may be mentioned:

Simplicity, there being no levers, rods, pivots, etc., to loosen and get out of adjustment. Positive action in both opening and closing. A positive holding of the valve partially open, for continuous drainage, as in washing out the basin, the friction of the serpentine thrust-member holding the parts at any desired position. The device is also fool-proof, since nothing can be done with it by the operator except to lift and depress a knob. A test of its durability shows the equivalent of twenty years actual service. It construction is such as to render it leak-proof, with no nuts to loosen or packings to depreciate. Its simplicity of course tends toward economy in manufacture, as well as efliciency in service.

Having thus described my invention, I claim: v

1. Combined with a lavatory waste-valve having a depending stem, ,a seat therefor provided with a guide for said stem, a flexibie pull-and-thrust member attached to the stern below said guide, a tubular guide for said member, and means attached to the free end oi said member for operating the same to open and close the valve, the valvestem guide forming a stop to limit the lift of the valve.

2. A waste-valve controlling device, comprising a valve having a depending, detachable stem, a guide therefor inside the valveseat member, a clamp-collar below said guide, a flexible thrust and-pull wire at? tached to said collar, an inclined and curved guide-tube for said wire entering at one end through the side wall of the valve-seat, a tubular support for the upper end of said tube, an operating knob with a stem slidable in said tubular support, and means for connecting the upper end of said wire adjnstably with said knob.

3. In a device of the character described, the combination of a pipe section adapted to be connected to the lavatory outlet, a stem mounted for movement axially of the pipe section and having a plug co-operating with the upper end of'said section to open or close the smile, a comparatively small tube extending through the side of the pipe section at an oblique angle thereto, a sleeve adapted to be secured through the rim of the lavatory, a coupling for securing the lower end of said sleeve to the outer end of the tube, a knob having a downwardly projecting hollow rod reciprocable in said sleeve, a flexible wire extending through the tube and attached at its inner end to said stem, and means for adj ustably securing the outer end of the wire within said hollow rod, whereby the reciprocation of the latter will open and close'the plum In testimony whereof I aflix my signature in presence of two witnesses.
